We can go back and forth on this without ever reaching an agreement, but your comparison is not apt. It's like saying that PCs and laptop sales do not effect each other. Your analogy is not even close.

Tell me what from that will be both big and exclusive, which is required for a game to push hardware. Forza 4 is the only one I can see there and it's not the first on the 360 so hardware impact will be low. That is of course unless MS can convince the casual market that Kinect is superior to the Wii.
So you're saying that Moore's law has finally broken! That is indeed an amazing claim, for which I would require much more than you merely claiming it in a forum post with no evidence. Fact is, technology is advancing now as quickly as it was last gen, and the gen before etc, thus this gen, from a technical perspective, has no reason to last longer than the previous one.
Your attitude towards motion controlled gaming just goes to prove my point. There are sensible ways to make motion controlled games, and then there are the ways you mentioned - devs need experience with motion controls now to make good games next gen.
Additionally, you are either mistaken about the meaning of the word 'precision' or about the specifications of the 3 major motion controls. I can guarentee that motion controls are more precise. In order to turn full lock on a racing game (assuming we're talking about one that is controlled using a motion controller to mimic a steering wheel) you must move your hands aprroximately 20 cm. In order to provide the same lock from a control stick, you must move your thumb approximately 2 cm. If you move 2 cm in the motion controlled case, you get 1/10th lock. This means that a motion controller is, in this example, 10 times as precise
However, I shall give you the benefit of the doubt and respond as if you used the word accurate, which actually means what you think precise means. In that case, I would say that you have no had enough experience with PSmove, the Wii motion or Kinect in order to judge how accurate they are, because, frankly, if you had, we wouldn't be having this conversation. That is why it is vital that MS and Sony get their motion controllers into the hands of as many gamers as possible - they need to show what an advantage it gives you in competitive play, and how fun it is in social play. You are the reason kinect is out now.
